Hello, I am experimenting with at-least-once-delivery in akka-persistence. My goal is to create a future-based service layer on top of an actor system by using AskSupport.
The deliver method in AtLeastOnceDelivery expects an ActorPath as its message destination and delivers the message by using tell on an ActorSelection created from the ActorPath. Using tell on an ActorSelection always results in a TimeoutException in my unit tests if the target of the ActorSelection is a temporary actor created by AskSupport. I created a test-case on github that can be used to reproduce the problem: https://github.com/ferdinandhuebner/akka-asksupport-actorselection Here's a direkt link to the test-suite: https://github.com/ferdinandhuebner/akka-asksupport-actorselection/blob/master/src/test/scala/ActorSelectionVsAskSupportSuite.scala I tested with Java 1.8, 1.7 and akka 2.3.8, 2.3.7, 2.3.4 and 2.3.2, the result is always the same. Is this an expected behaviour of ActorSelection and temporary actors created through AskSupport? What I can tell from debugging the code: ActorSelection#deliverSelection doesn't seem to be able to resolve the temporary actor. After a few recursions it ends in a case that is commented with "foreign ref" and calls tell on an ActorRef [akka://test/temp] instead of [akka://test/temp/$a] I added another test-case with a proxy intermediary that receives the message from the AskSupport actor and sends it to the desired target. That code works fine. However, I want to avoid creating proxy actors. I don't think that I'm accidentally blocking somewhere in my test-code, since the test with the proxy actor runs fine. If anybody can share any hints or feedback, I would appreciate it.
